The present invention relates to improvements in stud and spring socket fastenings and is applicable for use on handbags and other articles or containers in which such fastenings are necessary or desirable.

Briefly stated thepresent invention comprises a fastening of this character with a double action adapted to be first unlocked and then disconnected by continuous pressure on the stud; The stud comprises an element, a sleeve and a spring working in a cylinder.

According to the invention the stud and an inner-unlocking sleeve are mounted on a spring and the combined member is adapted to be pressed back against the influence of said spring through an opening in the socket to release the stud from the socket grip.

Our invention is shown by way of example 1 in the accompanying drawing, in Which- Figure 1 shows a sectional view of the stud and spring socket fastening in the fastened position. 7

Figure 2 shows a plan view of the stud.

Figure 3 shows a section on the line III III of Figure 2. 1

Figure 4 shows a sectional side'view on the line IV-IV of Figure 3.

Figure 5 shows a plan view of the spring socket fastening with the cover removed to show the working parts.

Figure 6 shows a section on the line-VI- 5 VI of Figure 5.

Figure 7 shows a sectional view, with the spring omitted, of the parts in the first intermediate position of release, and

Figure 8 shows a sectional view of the parts shown in Figure 7 in the second intermediate position of release".

In the drawing 1 indicates the stud and 2 the spring socket shown'moreparticularly in Figures 5 and 6. As shown in Figure 1 these members are mounted on the parts to fastened. In a leather bag, forinstance, the stud is mounted on the body portion?) while the spring socket or fastening is mounted on the flap portion 4:, the body and the grip may be secured to the fasteningzdevice by Fig. 6 of the drawing.

oe engaged of the container. or bag vto be ras'rnmne clamping as'indicated'in Fig. 1, the clamp portion being secured by rivets shown in The element 1 of said stud is preferably spherical shaped as shown'and is developed" into a neck of cylindrical format the lower 'end which telescopes into the cylinder mounting 5, and is slidably supported there- 'by by the projecting lugs 7'on opposite sides which engage and slide in the slots 18 in the" cylinder 5. The element 1 is hollow and forms a sliding support for the'sleeve 12 which is provided at its upper end with a rounded, or-domed head. This sleeve projects through the element as indicated in 5 Fig. 4. The integral construction of the stud requires that the slidingmotion of the sleeve 12 be-limited relative to the element 1, as for instance between the upper posi-, tion indicated in Fig.3"and the lower position indicated in Fig. 8. In order to limit the outward sliding movement ofthe sleeve 12 with respect to the element 1, the ends of the spring 6 are suitably secured to cylinder 5 and sleeve 12 respectively. The coil spring 6 engagesthe bottom. 'The spring grip fastening is conveniently inthe form of two engaging members 8 with cut out portions 9 therein adapted toengage around the neck of the element 1 and to enter the slots 13 therein when in the fastened position shown in Figure 1'. Thesemembers 8 slide in the frame 11 and are under the influence of their bow springs'lO and consequently are, held up against the neck of the element in" engagement in the said slots 13 when the parts are in the fastened position.

As shownmore particularly in Figures 1, 7 and 8, the end 14 of the domed sleeve 12. o is turned inwards and the engaging edges' 15 of the gripping members 8 are chamfered in order that the members 8 may be easily pushed apart by the sleeve 12 when thelatter is pressed into the element 1.

In order to fasten the flapa to the body ofthe container'or bag the spring socket mounted on the flap is pressed over the stud, thus opening apart the locking members 8 as the studhead passesthrough the,

Opening The engaging ges 15 of the members 8 grip the neck of the element and enter the slots 13 therein as shown in Figure 1 and thus positively fasten the flap to the body of the bag. WVhen it is desired to release the fastening the domed end of the sleevelQ isgpressed and: the sleeve pushed down into the element againstzthe infiuence of the spring 6 thus pushing the membersS apart as shown in Figure 7 and allowing the element '1'"to be pushed through *the fgI'lP *fastening, into'the cylinder 5thus easily "and instantaneously releasing the flap from the body of the bag. or the like.
